How to Match LUMIX S5IIX V-Log and Sony A7 IV S-Log3 Footage
Mixing cameras is often the practical choice on a real production. One camera may be better for a locked-off interview, another for a handheld cutaway. The problem appears in the edit when skin, contrast and colour jump at every cut.
The LUMIX S5IIX and Sony A7 IV record different LOG systems. Matching them does not mean giving both clips the same LUT and hoping for the best. I would begin by interpreting each recording correctly, then make the images agree on the important things before introducing a shared creative finish.
Start with the actual recording settings
For the LUMIX clip, confirm that it was recorded in V-Log and note any relevant gamut or monitoring transforms. For the Sony clip, confirm S-Log3 and its recorded colour gamut rather than relying on the camera name alone. Different recording modes can produce different starting images.
Also check whether either file has been processed on export or baked with a look. If one source is already normalised and the other is still LOG, treating them identically will create a mismatch before the grade even begins.
Normalise each camera separately
Choose a deliberate technical conversion for each source, either through a correctly configured Resolve colour-managed workflow or an appropriate manual route. If you use ToneLab Chroma conversions, confirm the exact supported input and avoid adding a second transform on top of Resolve’s existing conversion.
The goal at this stage is not to make the footage cinematic. It is to bring both sources into a consistent working and viewing context. Once the technical interpretation is sound, exposure and colour differences become easier to judge.
Build a reference around faces and neutral objects
Choose one representative shot as the reference. If the sequence contains a person, compare skin under similar lighting. If it is a product film, use a neutral surface or familiar brand colour. Compare both clips on the same calibrated display and with the same output transform.
Do not expect different cameras to become identical when the lighting changes. A warm interior should still feel warm if that is what the scene looked like. The aim is to remove distracting jumps, not erase the character of the location.
Match the structure before the palette
I would match exposure, black level, highlight behaviour and overall contrast before chasing individual hues. Then check white balance and the way skin or neutral surfaces render. Resolve scopes help reveal differences that can be hard to see when you stare at one frame for too long.
Only after those corrections would I introduce a creative look. A shared look can help unify the edit, but it cannot repair a poorly matched technical starting point. If a preset shifts one camera’s skin too far, adjust that camera’s balance rather than force the entire sequence into the same compromise.
Review the cuts in motion
Park on the transition between the two cameras and play back repeatedly. Watch the face, the background and any repeated object. If your attention jumps to the colour change rather than the story, the match still needs work.
Check both wide shots and close-ups. A grade that seems consistent on two similar frames may diverge when the framing, lens or lighting changes. Matching is a sequence-level task, not a pair of still-image comparisons.
What ToneLab can and cannot simplify
Chroma is relevant because it can provide a repeatable route for supported camera conversions and creative finishing. That can reduce setup friction when several camera systems appear in the same project. It does not remove the need to verify source profiles or make per-shot balancing decisions.
For a working filmmaker, that is the useful distinction. I want the technical stage to be predictable so I can spend more attention on continuity, skin and the feeling of the finished film. The final judgement still belongs to the person grading it.
Frequently asked questions
Can one LUT match Sony and LUMIX LOG?
Not reliably as a technical starting point. Interpret each camera’s recorded gamma and gamut first.
Does the Sony A7 IV use S-Log3?
Yes, when recorded in an S-Log3 picture profile. Confirm the accompanying gamut for the exact clip.
Should I match exposure before colour?
A controlled exposure and contrast foundation usually makes later colour matching more predictable.
